    @hmcl and all, the new spout is fit for the at least once semantics and works fine for us, thanks a lot! Very recently one of our key customers asked to use a at most once implementation. Do we have any plan to have a at-most-once implementation? They set the topology.acker.executors=0 and found the spout is not working. Could you please help to evaluate - 1, will we implement this? 2. roughly how long time needed? Thanks
    
    **Requirement from customer** - \u201ctopology.acker.executors\u201d is a Storm parameter, which refers to at-least-once when it\u2019s not 0, and at-most-once if it\u2019s 0. We want to know do we have a at-most-once implementation?
